As we mentioned in yesterday’s iPhone 4S case roundup, your old iPhone 4 cases are going to work just fine on Apple’s latest model. But that’s not stopping developers from rolling out new models in honor of the occasion, or just reminding us of what’s already there. And today, we’ve got announcements from Marware, XtremeMac, The Callet, Belkin and GelaSkins.

Belkin, maker of all types of accessories for laptops, iOS devices, and Android devices, is having a sale until September 30th. Not just any sale, but a 50% off (almost) everything sale with no minimum purchase. All you have to do is use the coupon code FB50 when you check out on Belkin’s online store. The only bad news is that Belkin’s web site has been inundated with shoppers, so it may take you a few tries to get in.

One of the selling points for the recently updated Apple Cinema Display is that it also acts as a hub for additional devices with USB 2, Firewire, and Gigabit Ethernet ports. What if you want those ports but don’t need the monitor to go along with it? Belkin hopes to satisfy your need with its new Thunderbolt Express Dock it showed off recently at the Intel Development Forum.

Charing your mobile devices is one of the ugly necessities of modern electronics. We’re only portable for as long as we’re powered, after all. There are a lot of ways to get this done, most of which are quite messy and sometimes take more power than they need. To combat this, we’ve got the Natural Charles Charging Station Hutch and Belkin’s Conserve Wallet.

Belkin’s Access Folio Stand for iPad 2 has some really nice design elements, and it includes a couple accessories that some other folio developers leave out. It’s rugged, it’s smart looking, and it’s relatively thin. Unfortunately, there are couple awkward elements, too, that prevent me from recommending this as much as I could have.

What’s more important to you? Do you want a router that’s headache free during installation, or do you want a router that’s headache free after it’s set up? I guess it doesn’t really matter, because the Play N600 HD Wireless Dual-Band N+ Router provides both. Whether you’re ready to upgrade or looking to just now go wireless, you really should consider the Play N600 HD.

Of the many ways to protect my iPhone from scratches and scuffs, I think my least favorite is the clear plastic case. I understand the appeal of letting your iPhone’s design show through its protective shell, but the flaws inherent in clear plastic outweigh the benefits for me. Still, if that’s your thing, here are a couple to consider: Belkin’s Shield Micra, iLuv’s Glacier Ultra Thin Clear Case, and one bonus suggestion.

What to choose, what to choose… Apple is offering seven cases as part of their iPhone 4 Case Program to allay complaints about the iPhone 4 antenna. But which one should you take? Well, we haven’t tried them out yet, but because we like to be useful, we’ve rounded up some details on each to help you make an informed decision. I know which one I want…

iPod and iPhone cases are cash bonanzas for third-party manufacturers, so it’s no surprise so many companies were quick out the door with their iPad cases. Now that we’re already inundated with options, where do you start to look for a model that suits your needs and tastes? As always, a good place to begin is Belkin. Here’s our look at their Pleat Sleeve and Grip Sleeve for iPad.

One of the features I consider in iPhone case reviews is whether it comes with a method to attach the case to a belt, pocket, purse strap, or what have you. Few of them do anymore, but thankfully there are a good number of belt clips designed to work with at least the slim iPhone cases. In this review, I’ll take a look at offerings from Belkin, Speck and Monster.
